Wang and his Iranian counterpart Mohammad-Javad Zarif held a phone conversation on Nov 16 over the Iranian nuclear issue.

The six countries — Britain, China, France, Germany, Russia and the United States — are holding talks with Iran in Vienna. It is hoped that a comprehensive deal would be reached by Nov 24 that would ensure Tehran’s nuclear program is totally peaceful, while, in return, Western states would phase out sanctions that have severely damaged the gulf nation’s oil-dependent economy.
